v0.dev Not Working?
Blank output, credits gone, component not rendering in your project, or clipboard not copying? Check live status and fix it fast.
Current Status
v0.dev has two failure surfaces — check both:
What's Wrong? Diagnose Fast
Blank or empty output
Prompt too vague. v0 needs specifics: framework, component type, fields, styling library. Try: "React login form with email/password, error states, shadcn/ui, Tailwind, dark mode."
Credits exhausted
Free plan: 200 generations/month. Each generation + each iteration costs 1 credit. Check balance in account settings. Credits reset monthly.
Component not working in project
v0 generates shadcn/ui code. Your project must have shadcn/ui installed and configured. Run npx shadcn-ui@latest init then add missing components.
Copy button not working
Browser blocked clipboard access. Click Allow when prompted, or switch to Chrome/Edge. Firefox's Enhanced Tracking Protection can block clipboard APIs.
Step-by-Step Fix
- 1
Check live status
Visit prismix.dev/guides/v0-status and Vercel status. If either shows an incident, the problem is upstream.
- 2
Check your credit balance
Click the account icon in v0.dev. Free: 200/month. If you're at 0, wait for your monthly reset or upgrade to Pro ($20/mo). Check your billing date — credits reset on that date, not the 1st of the month.
- 3
Write a better prompt
Blank output means the prompt is too vague. Include: component type (table, form, modal), framework (Next.js App Router), styling (Tailwind + shadcn/ui), states (loading, error, empty), and data shape (fields, types). More specific = better output.
- 4
Set up shadcn/ui in your project
Run these in your Next.js project:
npx shadcn-ui@latest initThen add the specific components used:npx shadcn-ui@latest add card button input table - 5
Fix clipboard issues
If the Copy button doesn't work: click the lock icon in the address bar and Allow clipboard access. Or manually select + copy the code (Ctrl+A in the code block, then Ctrl+C). Firefox users should switch to Chrome for full clipboard API support.
Setting Up shadcn/ui for v0 Components
v0.dev generates React components using shadcn/ui. If you copy a v0 component into a project without shadcn/ui, you'll get missing import errors. Here's the quick setup:
1. Create a Next.js project (if you don't have one)
npx create-next-app@latest my-app --typescript --tailwind --app 2. Initialize shadcn/ui
npx shadcn-ui@latest init 3. Add the components v0 used (check the import lines at the top of v0's output)
npx shadcn-ui@latest add button card input table dialog badge 4. Copy the v0-generated file into src/components/
npm run dev Writing Effective v0 Prompts
❌ Too vague (blank output)
- "a dashboard"
- "user profile page"
- "login form"
- "data table"
✓ Specific (good output)
- "Next.js admin dashboard with sidebar nav, user list table (name/email/role), and a KPI card row at top, Tailwind + shadcn/ui, dark mode"
- "React login form with email + password fields, loading state button, error banner, shadcn Card wrapper, Tailwind"

View v0.dev Status →Frequently Asked Questions
Why is v0 not working?
Common causes: platform outage (check prismix.dev/guides/v0-status), Vercel infrastructure down (check prismix.dev/service/vercel), credits exhausted (200/month free), prompt too vague producing blank output, or shadcn/ui not set up in your project.
Is v0.dev down right now?
Check prismix.dev/guides/v0-status for live status. Also check Vercel status — v0.dev runs on Vercel AI infrastructure, so Vercel incidents affect v0 generation even if the UI loads.
v0 generating blank output — how to fix?
Make your prompt more specific. Include: framework (Next.js App Router), styling library (Tailwind + shadcn/ui), component type (table, form, modal), fields/data shape, states (loading, error), and any constraints (dark mode, responsive). Vague prompts = blank or minimal output.
How many credits does v0.dev give for free?
Free: 200 generations/month. Each generation costs 1 credit. Each iteration (asking v0 to modify an existing component) also costs 1 credit. Pro ($20/mo): unlimited. Credits reset on your monthly billing date, not the 1st of each month.
v0 component not working in my Next.js project — why?
v0 generates shadcn/ui components. You need shadcn/ui installed: run "npx shadcn-ui@latest init" and then "npx shadcn-ui@latest add [component]" for each component v0 imports. Check the import lines at the top of the v0 output to see which components you need.
